摘要
射精管梗阻是导致男性不育的重要原因之一。根据病因可分为先天性梗阻和继发性梗阻两类。通过病史、体检、精液分析和经直肠B超检查可为本病诊断提供重要依据。精液检查见四低(精液量少、无精子或少精子、pH值低、精浆果糖水平低)是其特征性表现。锝(99Tcm)硫胶体精囊闪烁扫描对功能性梗阻、部分性和完全性梗阻的鉴别有重要价值,经皮穿刺输精管造影、穿刺精囊抽吸精囊液及造影可明确诊断。经尿道微创外科治疗可使部分患者获满意疗效,术后仍不能生育者可行辅助生殖治疗。
Ejaculatory duct obstruction （EDO） is an important cause of male infertility. Etiologically it can be either congenital or acquired. The diagnosis of EDO mainly depends on history,physical examination,semen analysis,and transrectal ultrasonography （TRUS）. The semen of EDO patients is characterized by low ejaculate volume,oligospermia or azoospermia,low pH,and absence of fructose. Technetium （99Tcm） Sulphur Colloid Seminal Vesicle Scintigraphy is of great value in the differential diagnosis of functional,partial and complete obstruction. Definite diagnosis of EDO can be established by vasography,seminal vesicle aspiration and seminal vesiculography. Transurethral resection of the ejaculatory ducts （TURED）,as the standard method of treatment for EDO,is effective for many of the patients. And the assistant reproductive technology （ART） is required if the procedure fails to restore the patient＇s fertility.
